A mouse arrow cursor 603 b for indicating the position of the upper ball indicates a center circle of the field 602.
[0050]
The coordinates on the field 603 are expressed in a logical coordinate system with the center of the center circle 603b as the origin (0, 0). The coordinates of the intersection of the end line and the touch line are (−500, 350), (−500). , −350), (500, −350), and (500, 350). This is an actual soccer field (100 m × 70 m) represented in a logical coordinate system.
[0051]
The operator traces the actual ball position with the arrow cursor 603 by operating the mouse on the field 603 of the ball position information input screen 600 while watching the soccer game on the monitor or on the spot. When the team A keeps the ball, the operator left-clicks the mouse, and when the team B keeps the ball, the operator right-clicks the mouse.
[0052]
The ball position information acquisition / dominance rate measuring unit 101 samples the position of the arrow cursor 603 on the field 603 of the ball position information input screen 600 at a predetermined time interval (for example, every 1 second) to obtain ball position information (time information). , Ball position coordinates), and the acquired ball position information is displayed in the information display area 604 of the ball position information input screen 600.

In addition, using the acquired ball position information, it is possible to easily create a formation diagram, a ball transition diagram, a dominance map, etc. to express the soccer game situation, making it easy to analyze soccer tactics, etc. Can be done.
[0059]
In addition, since the field 603 has a coordinate system having the center of the center circle 603a as the origin, the coordinate position of the ball can be simply expressed by “+” and “−”.
[0060]
In addition, since the ball dominance information indicating the ball dominating team is acquired in accordance with the operation of the mouse (coordinate position input means) by the operator, it is possible to easily acquire the ball dominating team. More specifically, while the left click of the mouse (first operation) acquires the ball control information indicating the ball control of the A team, the right click of the mouse (second operation) indicates the ball control of the B team. Since the ball control information is acquired, it is possible to easily acquire the ball control information indicating which team controls the ball with a simple operation of the mouse. As a result, it is possible to easily calculate the ball dominance rate using the ball dominance information.
[0061]
Since the acquired ball position information and ball control information are displayed in the information display area 603 of the ball position information input screen 600, the operator can confirm the acquired ball position information and ball control information. It becomes possible.
